I checked them out myself. We can also graph inequalities on the number line. But now with the Algebrator I learn and complete my homework faster. It cannot be any other number except for 2.

Graph of the Inequality x < 3.

I brought home my first A in math yesterday and I know I couldnt have done it without the Algebrator.

In the end, you can use a pretty straight forward formula to solve quadratic inequalities. To aid the process of solving an inequality it is important to provide a clear writing frame to show how the inequality remains balanced as it is simplified. Thus, to graph an inequality with a " ≠ " sign, graph the entire line with one point removed. In the examples below, we show the range of true values for a given inequality. What is the solution of a quadratic inequality? If you had to graph x = 2, that means that x must be exactly equal to 2. My parents are really happy. John Tusack, MI, Every time I tried to do my algebra homework it took hours for me to finish it. For example, the graph of x ≠ 3 looks like −, Graph the following inequality on the number line −.

Before we graph an inequality on a number line, let's look at how to graph an expression with an equals sign. Students are familiar with the balance method from solving two-step equations. We graph numbers by representing them as points on the number line. This time, we need to draw the ray to the left to indicate that all the numbers smaller than 2 are solutions to the inequality.

If we pick any number on the dark line and plug it in for x, the inequality will be true.
